You don't need a big press for polybushes, they go in real easy, just grease and fingers.
To get the old ones out you need:
penetrating oil applied to the old bolts for several days before. (buy new ones as you will probably have to cut or grind the old ones off)
Grinder to grind old bolts off
Blow torch to apply a bit of heat to bolts to get them off and also to burn the old rubber off the old bushes so that you can get them out. I found the only way to get the bushes out was to burn them.
Lots of change to go in the swear box
big hammer to hit things when you get really pi**ed off with the bolts and bushes that don't come off
Strong socket set with massive bar to shift bolts
Copper grease so that when everything is put back together it should be easier to tack off again in a few years time.
But the new polybushes go on very easily.
Did I mention that getting the old bolt and bushes out can be hard?
